Audible and Amazon yesterday launched two new features exclusive to Kindle: “Immersion Reading” and “Whispersync for Voice.”

Whispersync for Voice builds on Amazon’s current Whispersync technology that enables customers to switch — without losing their place — between different devices while reading a Kindle book or to start watching a video on a Kindle Fire and pick up where they left off on a TV.

With Whispersync for Voice, Kindle and Kindle Fire users can now switch seamlessly between reading a book and listening to the Audible audio edition on any iOS or Android phone — all without losing their place.

“The ability to seamlessly switch back and forth between reading text on any Kindle and listening to the same title in audio on your smartphone — and always pick up where you left off — means that the story can continue during those times of the day when you cannot look at a screen,” said Audible Founder and CEO Donald Katz in a statement. ”We think that Whispersync for Voice can help us all enjoy more books, which is good news indeed.”

With Immersion Reading, Kindle Fire and Kindle Fire HD owners can synchronize Kindle text with the corresponding Audible audio edition. As customers read their books on Kindle Fire, text is highlighted while it is narrated via the Audible audiobook.

“We’re excited today to unveil our latest innovations that will help people read more and retain more of what they read,” said Amazon Founder and CEO Jeff Bezos in a statement. “Anyone who wants more time to read, or never wants to put a great book down because it’s time to drive to work or exercise, will love Whispersync for Voice — it offers our customers the profound gift of more time to read.”

Nearly 15,000 Kindle books and Audible audiobooks are available for Immersion Reading and Whispersync for Voice. Plus, Amazon and Audible are inviting customers to try both products for free for a limited time with 20 Kindle and Audible tiles, including Adventures of Huckleberry Finn (narrated by Elijah Wood) and The Wonderful Wizard of Oz (narrated by Anne Hathaway).
